No. The t case wears through after a lot of mile. My 03 is quick. Long bed dually crew cab. Love the truck. Put ~30k on it. It now has almost 200k on it and it starts great, runs great, pulls great. Don't know if the injectors were replaced or not. More than likely. I just ordered a fass fuel system for it. Help save the cp3 and injectors. I service my filter every 10k so I haven't seen any dirt in my intake yet. So I'm gonna keep running the k&n for now.
